Was in X Men 3 Logan Kills Jean Grey

Logan kills a lot of people but none matters more than this one Jean grey in the films hosts the phoenix force but she never actually controls it Charles Xavier knew it from day one and tried to protect her but in the last stand she's really let loose the phoenix force comes out in all of its glory and it's frighteningly awesome as Logan realizes that gene can never control it putting an end to it is the only way so that means killing gene the person Logan loves though jean grey attacks Logan with her full force and Logan recovers the cycle repeats until Logan gets to gene and then kills her.

Logan Surviving Professor X Attacks

We didn't really see Charles Xavier using his telekinetic skills to wreak havoc well apart from that extinction level Logan gave us a much better depiction of what he's capable of when his seizures would trigger psychic waves of destruction Logan handled it pretty easy the first time because he was physically closer to the professor  in the hotel room, seizure was so powerful that it actually froze everyone within the vicinity and only Logan could walk all the way to the room to stop the madness plus he killed all those assassins for good measure too and this was when his regenerative powers weren't even at half capacity.

Wolverine Meets Beast

Wolverine meets Beasty wolverine time travels like a pro from a young beast being a scrawny little late bloomer to old magneto realizing his mistake moments before expecting to die at the hands of the sentinels Logan is everywhere the fun fact is that Logan knows all these people but not many actually recognize Logan so when Logan sent back to the 70s to stop the sentinel program he heads straight to the x-mansion young Charles is deluded lazy and cranky and beast is just a cute little caretaker boy so Logan doesn't miss the opportunity to make fun of a young beast and he does it ever so elegantly.
