Machamp (or called by his nickname Bro) was one of the two Pokemon Robbie E first received as a Machop. Robbie E has had Bro since he joined TNA, which he was a Machoke at the time. Due to his poor battling and not focusing in battle, Bro did not evolve into a Machamp until the beginning of Season 4. Bro has the same personality as his trainer... stupid. It seems he focuses more on showing off then he does battling. He does have powerful moves he can use... but he hardly ever uses them because he isn't thinking.
James Storm's Swampert
Eric Young's Mamoswine
Joseph Park's Lopunny
Because of Bro's stupidity, he doesn't really have that many allies.
Jessie Godderz's Poliwrath
Zema Ion's Quilladin (Spike)
Robbie E received two Machop at the same time; a normal one and a shiny one. Both Machamp constantly argue over who is the better looking one.
It has been revealed that Bro has a very low IQ and a new running gag has started recently with wrestlers and other Pokemon making fun of his stupidity. This running gag has replaced the James's Swampert's stupidity one since Swampert has gotten smarter.
Bro got his nickname because of Robbie E constantly calling everyone "Bro".
