The most obvious of which is Connor. And while in the TV series - Connor grew up to become Angel's misguided son, although they eventually made peace by the end of Season 5.
For the Ultimate'verse version of Connor - I'm thinking a completely different angle - as his biological parents are Darla & Angelus. This version of Connor would eventually become like a Vampiric messiah - and be a Big Bad in one of the later seasons (such as season 8 or beyond).
Another child I want to introduce to the series - is a character that was briefly introduced in my Children of Destiny series - Kathleen(named for Angel's sister). In Children of Destiny - Kathleen was the daughter of Buffy & Angel (some 20 years in the future) - She was a teenage(16-18 years old) Vampire Slayer, with qualities from both her mother(slayer abilities) & Father(Acute Senses & photographic memory). In the Ultimate series - the basic charactristics of Kathleen the same - i.e. parentage, and abilities(as a teen) - but I plan to introduce her at the beginning of Season 6 as a child. Also it's possible I may change her name as well.
While Connor's rapid growth rate is already planned. I'm less clear on how to go about Kathleen's growth rate. But I am sure that I want her to have some kind on increased growth rate. Other wise - she could spend the next 5-8 seasons as a pre-teen.
1 option - is that because of her unique parentage - that she matures in about half the time as a normal human would - basically taking about 7 years(the 1st 4-5 of which are spent in the Slayer realm) to go from infant to 14 yr old. From 14-21 she ages like a normal human. From 21 on she ages at about half the normal human rate.
2nd - she ages normally - and has to enter another dimension(like the Slayer realm) to quickly become a teenager.
Or if you have another suggestion -please add.
