Wohoo! I fixed a bunch of her! Changed the spikes on her breast plate to silver claws, increased her arm length and fixed the weird angle which came from the connection joints, changed up her waist and such a bit (but I still feel it needs changing) and also gave her better legs! Thanks to @Jal for the leg idea. Also I do want to possibly custom make the lower torso but I have very little ideas on how to so any you have/know about let me know and I'll see what I can do.
She has essentially gone from normal toa to titan toa in just two days! I'm actually going to incorporate this into her backstory and how she met Qadoentra now!
As said before Qadoentra finally caught up with Tekal after she had left the group for a bit to do a side mission of her own. The side mission was actually why she is now a Titan, she had always felt herself as a liability to the team, despite her amazing gun precision and agility, due to her below average strength. During the misfits travels she heard rumours of a powerful item that would turn a toa into their Titan form, increasing the abilities, but was also heavily guarded by strange, sentient rahi, traps and possibly makuta. After hearing about it she decided to find it so she could become a titan so her strength would increase and she'd be less of a liability to the team. She eventually figured out where it most likely was and when her team was near that area she left to find it. She did manage to get to and use the item, albeit taking quite a bit of damage beforehand, the rumours of how it was guarded all being true and then some.
While it did increase her strength it was less than she expected, putting her at about the average toa’s strength, so while she's still quite weak she was strong enough to no longer be a liability. She the met Qadoentra before both of them headed back to her team and they discovered what she had done, while they were happy she was stronger they all were somewhat upset that she considered herself to be a liability, her having already proven herself to be amazing asset in battles, and that she had almost died doing so.

Update: XD! Literally just noticed I put the legs on wrong! The red one is supposed to be her left leg not right one!
