A1: Jump when he does fire thingy shoot him and hide behind portal when he fires the orb he shot will hit him do this 3 times then he climb to top keep jumping over his flames and hit em when hes defenseless then press x o and that stuff then when the flashing x comes you just keep hitting x until it damages him and do this until you win

A2: A1: When you get to where he is when he stoots the fire balls at you doge them when you are in front of one of the teleporters and they will come behinde them and hit him and when there is only one teleporter left he will jump higher on to the piramid and then you will go to him and when he hits his fist/foot on the groung jump at him and then you can hit him then you have to press the buttons it says to push then he fall on the ground ( oh and on the last button you push you have to tap it a bunch of times ) and you can hit him and you just keep doing that until he is dead
A2: I think the fallen is easier than Magatron!

A3: On the last part before he dies I barley got hit by him, heres how: when he shoot at you just dodge and shoot him ti he pounds his fioot on the ground and when he does that jump in the air twards him and attack whie in the air then run and shoot and repeat.
