Erik's showings and power descriptions are all over the place.
Normally, he would be unable to deal with hulk. If we talk about some of his peak performances and more high-level stats, he could do some damage.
Theoretically, he can grow large enough to defeat Hulk and could possibly attain the same kind of unlimited power the Hulk and others boast. That, along with enormous size, could make him a winner.
The larger he gets, the more his power increases. Growing stronger and more durable. Making him more difficult for a small Hulk to exploit hidden weaknesses, such as the kind that he has found on other giant enemies in the past.
Yeah, he was koed. I have been looking for the last scan in my files but I can't find it. He was koed though. If someone can post it, that would be amazing.
