Problem: Terry Eugene Bollea was born in Augusta, Georgia on August 11, 1953, the son of construction foreman Pietro "Peter" Bollea (December 6, 1913 - December 18, 2001) and homemaker and dance teacher Ruth V. (nee Moody; 1922 - January 1, 2011). He is of French, Italian, Panamanian, and Scottish descent. When he was one and a half years old, his family moved to Port Tampa, Florida. As a boy, he was a pitcher in Little League Baseball.

Hogan remained WWF World Heavyweight Champion for four years (1,474 days). In front of 33 million viewers, however, Hogan finally lost the title to Andre on the February 5 episode of The Main Event after a convoluted scam involving "The Million Dollar Man" Ted DiBiase and Earl Hebner (who assumed the place of his twin brother Dave Hebner, the match's appointed referee). After Andre delivered a belly to belly suplex on Hogan, Hebner counted the pin while Hogan's left shoulder was clearly off the mat. After the match, Andre handed the title over to DiBiase to complete their business deal. As a result, the WWF World Heavyweight Championship was vacated for the first time in its 25-year history because then WWF President Jack Tunney decreed the championship could not be sold from one wrestler to another. At WrestleMania IV, Hogan participated in a tournament for the vacant WWF World Heavyweight Championship to regain it; he and Andre were given a bye into quarter-finals, but their match resulted in a double disqualification. Later that night in the main event, Hogan came to ringside to stop Andre interfering which helped "Macho Man" Randy Savage defeat Ted DiBiase to win the title.  Together, Hogan, Savage, and manager Miss Elizabeth formed a partnership known as The Mega Powers. After Savage became WWF World Heavyweight Champion at WrestleMania IV, they feuded with The Mega Bucks (Andre the Giant and Ted DiBiase) and defeated them at the main event of the first SummerSlam. They then went on to feud with Slick's Twin Towers: Akeem and Big Boss Man.  In mid-1988, Hogan wrestled at house shows in singles competition with his "War Bonnet", a red and yellow gladiator helmet with a fist-shaped crest. This was notably used to give Bad News Brown his first WWF loss at a Madison Square Garden house show before it was discarded altogether. The War Bonnet gimmick was revisited in the WWE's online comedy series Are You Serious? in 2012.  The Mega Powers began to implode due to Savage's burgeoning jealousy of Hogan and his paranoid suspicions that Hogan and Elizabeth were more than friends. At the Royal Rumble in 1989, Hogan eliminated Savage from the Royal Rumble match while eliminating Bad News Brown, which caused tension, only to be eliminated by The Twin Towers himself. In early 1989, the duo broke up while wrestling The Twin Towers on the February 3 episode of The Main Event, when Savage accidentally collided with Miss Elizabeth during the match, and Hogan took her backstage to receive medical attention, temporarily abandoning Savage, who slapped Hogan and left the ring, where Hogan eventually won the match by himself. After the match, Savage attacked Hogan backstage, which started a feud between the two. Their feud culminated in Hogan beating Savage for his second WWF World Heavyweight Championship at WrestleMania V.

who else did he wrestle against?

Question:
A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers.
The four-piece band is the most common configuration in rock and pop music.  Another common formation was a vocalist, electric guitarist, bass guitarist, and a drummer (e.g. The Who, The Monkees, Led Zeppelin, Queen, Ramones, Sex Pistols, Red Hot Chili Peppers, R.E.M., Blur, The Smiths, Echo and the Bunnymen, The Stone Roses, Creed, Black Sabbath, Van Halen, Rage Against the Machine, Gym Class Heroes, The Stooges, Joy Division, and U2.) Instrumentally, these bands can be considered as trios. This format is popular with new bands, as there are only two instruments that need tuning, the melody and chords formula prevalent with their material is easy to learn, four members are commonplace to work with, the roles are clearly defined and generally are: instrumental melody line, rhythm section which plays the chords or countermelody, and vocals on top.  In some early rock bands, keyboardists were used, performing on piano (e.g. The Seeds and The Doors) with a guitarist, singer, drummer and keyboardist. Some bands will have a guitarist, bassist, drummer, and keyboard player (for example, Talking Heads, Gerry and the Pacemakers, Small Faces, King Crimson, The Guess Who, Pink Floyd, Queen, Coldplay, The Killers and Blind Faith).  Some bands will have the bassist on lead vocals, such as Thin Lizzy, The Chameleons, Skillet, Pink Floyd, Motorhead, NOFX, +44, Slayer, The All-American Rejects or even the lead guitarist, such as Death, Dire Straits, Megadeth and Creedence Clearwater Revival. Some bands, such as The Beatles, have a lead guitarist, a rhythm guitarist and a bassist that all sing lead and backing vocals, that also play keyboards regularly, as well as a drummer.
