TMNT Bayverse x Avengers, Tony Stark has a son, Lunar (Lunar is a 15 year old male with fair skin, freckles, a star shaped birthmark on his cheek, black hair with light blue streaks, starry blue eyes that have a bit of an electric crackle to them, he wears a white shirt with a blue letterman jacket, denim shorts, white sneakers, a blue bracelet that has a galaxy charm hanging from it, he also has a scar on his hand from the fire(when touching the doorknob to get out of the lab after he and April got the turtles and Splinter from back in the day with the fire thing and when the turtles and Splinter were just normal) and it being super super hot leaving a scar there), he also wears Star shaped earrings, a gift from his 15th birthday) is born that he is born with a star shaped birthmark and is named after the lunar eclipse!! Lunar and April were childhood friends and Lunar hanged out with April in her father’s lab where him and his associate Eric Sacks does experiments using this green ooze(aka The Mutagen) and a rat and 4 baby turtles(aka Splinter and the turtles) and of course April not knowing the affects puts a bit of this ooze on a slice of pizza for Lunar and well it gave him powers(storm based powers) , and one day there is a fire and Lunar and April back into the lab and saves the turtles and the rat(Lunar getting Leo and Splinter and April getting Raph, Mikey, and Donnie) and sets them free into the sewers where the mutagen took hold and now 15 years later, Lunar’s all grown up and he and April are fixing to reunite with the turtles(only Splinter remembers them of course since the turtles were babies at the time) and Donnie will start geeking out when he picks up that mutagen signature from Lunar and sees well the powers but Donnie will also question Lunar’s unique name and the birthmark. And now Lunar is apart of the craziness fixing to go down of stopping Shredder before he releases a toxin across New York City and stopping Sacks(who made the mutagen which is an antidote to this deadly toxin and of course it was destroyed in the fire and the turtles and Lunar are the only ones with it left in their blood) from selling that antidote, and now Lunar and April reconnect after so long since Tony seperated them after the fire and Lunar meets Vern and gets used to him and everything and when Vern starts questioning things and doesn’t start driving both Lunar and Raph will demand that he starts driving NOW in perfect synchronization after saying a separate comment each and this is how Vern will figure out about the 5 extra passengers in his news van that April brought with her 4 turtles and one teenager with a storm brewing in his blood. But what happens when Lunar grows a bond with Leo and these two have a little bit of a special strong bond growing(since Lunar was the one that saved Leo and Splinter mainly) that may blossom into love, and when April and Vern sneak into Sacks lab and tries to steal files or get any information they can and start getting shot at, Lunar will come out of the vents and get the things Donnie needs before sending an electric shock through Sacks systems and frying the whole thing which gets Sacks attention before Lunar will notice the hidden journals and snag em since gossip, and Lunar gets out, while Vern is being a literal baby, and Lunar will say things about that and Raph will say things about that, as Lunar will throw Vern into the back and takes over driving and he floors it, and that gets Vern to scream
