Magneto probably not dead, Leech probably turn off his power.

Great take my friend. I didn’t even consider this after watching this episode 👍🏾

He's a leech for a reason😂😂

It's funny, I was kind of thinking this in the back of my head but didn't really formulate the whole thought conception that you just delivered. I was beginning to suspect though, that wouldn't this have caused some kind of problem for Magneto? Because it's not like leech controls his powers, I believe they are just always on. Truth be told though, with the range of power of that Super Sentinel, it looks like it was going to overpower Magneto anyways. Maybe Magneto in the comics would have taken it out, but it doesn't look like this version of Magneto has that level of power. At least it hasn't been fully displayed.

I think Leech can control his power dampening abilities. Otherwise, wouldn't every Morlock he's around be rendered useless? He's always within close range to them from what I remember (and even in this episode). Granted, I don't remember much of how his powers were in the original series and that should be what we go by. Maybe it's always active and he doesn't control it.

Is Leech the mutant from X3? Did they just make him look like a regular person?
