"It is I Iris, I have now taken this form to better assist you in the purification of this world." Apocalypse could do nothing but chuckle at Skaar's threats. He's been wary of Thor the minute he found Iris in Asgard and has taken the necessary precautions to do battle with an Asgardian.
"You're threats are absolutely hilarious young warrior. I've seen the world through my young Iris' eyes for the longest now. Do you not think that I would be prepared for the son of Odin? I have been returned to my former glory and I have melded myself certain artifacts into my arsenal. I will succeed, I will cripple the Summers bloodline. I have already killed his brother, taken control of his daughter and the rest will fall soon enough. You also can not kill Iris. You may try your hardest but you won't succeed. She is protected by such a mysterious force that it can only be defined as divine luck. My child here is destined to die a certain way, at a certain place and time. She's supposed to die for the greater good of the world. I believe that I am that greater good for this planet. Something will stop you from killing her like this."
Apocalypse uses his telekinesis to pull Skaar's blade from her throat and then pulls her into him. His cold hand gently wraps around her throat as his face delivers her a smile. "You're safe now my child, I will punish the prince on your behalf." He then looks at Skaar and starts altering his body in order to shift into the Hulk during his war against the world not too long ago. He then began increasing his strength and size and voice to match. "You want me to leave, then make me...Son."
