Ugh I know I said I got a break but I can't help but let myself infodump out of nowhere GAHHH
I'm too lazy and busy to make a proper image of him but this is my Self-Insert Ben 10 oc, Blake 15 !! It's literally just my Main Sona but as a Ben 10 oc BUT he's a lot more different than him !!
Despite being part of the omniverse AND being a Ben, Name is Blake!! Even so, he does have Benjamin in his name, just refers himself as his first name preferably
He first became "Blake 15" by finding his Omnitrix (Trix-F25, or Combatitrix) in a normal school field trip alongside his classmate and grandpa, since he just got the Combatitrix for the first time he freaked out and accidentally turned himself into Heatblast, causing destruction amongst a campsite his school visited which alerts his gramps and classmate, luckily Blake was not caught by his other classmates and teachers and was taken as a gas leak of some sorts. His grandpa knows about this device and explains to both Blake and said classmate of it's purpose and abilities, as the field trip gets cancelled and the trio get onto the RV to have their own trip instead.
There are around 24 aliens Blake is able to unlock, with a small chunk of aliens being species not seen in the prime/reboot series, around 6 of them have different names from their original counterpart (and his naming system is just as bad as Ben 23's) which includes :
Soundwave (Echo Echo)
Enormosaur (Humungosaur)
Bonecrusher (Wildmutt)
Shockatwist (Feedback)
Anglare (Ripjaws)
Titanicus (Way big)
About the Trix-F25, in Blake 15's universe, his Azmuth has made a few omnitrixes for different purposes/in an attempt to make a normal functioning, some were in affective or malfunctioning, some which he doesn't touch for his own personal, some..for other things! Trix-F25 was a sucessful prototype along with two other omnitrixes, and this being Azmuth's main focus, it is not just focused on attempting to make peace with other species by having the wearer transform into a million types of aliens, rather, because of it's other name Combatitrix, it focuses on showcasing the other combative skills of other species by letting the wearer have the strongest prime samples of multiple species in one device.
Although Azmuth deemed this to be dangerous because of the enhanced combative skills given to each DNA sample in the Combatitrix, he has his second assistant, Xylene, to give it to grandpa max, this ends in a battle with Vilgax and Xylene causing the Combatitrix to fall off the ship and land on the campsite, and now Azmuth, with just himself, has to go and try to take it back without alerting the power-hungry Vilgax who tracked the Omnitrix the whole time since it's creation.
Uhh YAP YAP YAPP basically Azmuth created the watch for the purpose to showcasing the combative skills of each alien, as well as giving some sort of boost to the samples to make them stronger than your average Omnitrix, this comes with an outcome though! It does take a mental toll onto Blake if he uses it to often and some of the alien's behaviour could bleed onto his human form, causing him to go berserk or just emotionally numb if used too excessively. I'll talk more about it soon BUUTT I gotta go, take all of this massive yappagraph for this specific Ben au :3
