While I'm at it, here's my other J&D OC, in written form this time!
(I don't have a name of a definite appearance for her, other than her purple hair. XD)
So my idea is that, Purple was an inhabitant of Sandover Village as well (could very well be possible since there was empty houses around all the villages in TPL). And she went to Haven city as well, BUT, through the long way. By that, I mean that, something happened at some point which made her able to "channel" (I guess that's the word?) the different types of Eco, which then made her not age anymore, so instead of the time travel, she just went through the whole creation and development of the city. Angst ensue, obviously. XD
About said Eco powers my idea is that, she can actually kinda stock up on the different kinds of Eco (to a certain limit), and they give her some physical boost (as well as a cool shade of lighting on her skin 👍 XD).
Red eco making her hit stronger, blue making her faster…basic stuff from TPL.
When her stocks are depleted, she can go to Eco sources to fill them back up, or meditate near plants for the green Eco for example.
Dark Eco is part of it too. She needs to stock up on that too cause it's needed to keep the other types of Eco balanced/in check. If her Dark Eco is depleted, the other Eco start to become uncontrollable.
. Now, back to story stuff! What happens in Haven City? Well, since her eco powers are useful to fight, she became quite a strong fighter for the city (wearing a special armor and stuff, how cool! 🙌 XD) So, as to not get her in his way (and to not mess with the canon story stuff XD), as well as in the hope that she wouldn't come back, Baron Praxis sent her, in some kind of far Wasteland filled with MetalHead nests, to destroy said nests. She would only come back after Jak 2 (or 3, not sure yet). She then would recognize the main cast of the game, be so happy to see them again, but they wouldn't recognize her (ah angst again~) which would put her in a bad mood afterwards. They would only recognize her after a while and some trivial matter (like "hey remember these fruits we ate in Sandover Village that someone brought back from the Borbidden Forest from time to time? Oh WAIT-"), making this very awkward. XD
And also (yes, there's MORE!), she would have also brought back from the Wasteland a Special Metalhead (who can shapeshift into a human)! Why? Well! As she was fighting in a nest, she fought a very strong MetalHead, to the point where they both injured each other pretty badly: her heart would have been stabbed, and would only be kept together by almost all of her Green Eco stocks, while his Head Gem would have been cracked, breaking his link with the MetalHead hivemind, making him able to think for himselfn but also turning him into an ennemi in the eyes of the other MetalHeads.
So, my OC and this MetalHead would have then started to help out each other, then came back to Haven City, where she would teach him how to act as a human better.
There we go! XD
