(Also I am going to be creating new races purely because I feel like tensura doesn't have enough of them and for time reference 3 years before Rimuru reincarnated just to give a little bit of a head start)
Daniel was in his home brainstorming ideas for his tensura character but Because of all the stress his heart disease reacted violently and shut down his heart lucky for him reincarnation was real and he was brought into the tensura universe if it weren't for that he probably be in the abyss by now but it's been 24 hours since his reincarnation that only because he was panicking but also because he was trying to figure out all the skills he had and how to use them.
His unique skill optimizer allowed him to optimize certain aspects of skills specifically the downsides but he could also copy and amplify skills but only for a short time and he could optimize magicules around him or his own to increase chances of getting a skill evolving or helping a subordinate evolve and the other unique skill he had was pride it would have a chance to take and permanently give him the skill and his final unique skill he got from eating an few corpses a few hours into his reincarnation the skill was scavenger it gave him a skill or muiltple If he ate a corpse and the number of skills or the success rate depends on how strong the opponent was during life.
As for his appearance he had a bulky body cube like yet strong head and long tails with spikes and short wing membranes although he could glide slightly he couldn't fly as he traversed a rocky platue using his raw physical body to climb steep cliffs and when an boulder came rolling down an cliff he caught it and stopped its movement before tossing it aside as Daniel travelled the land he was thinking about ways to gain power he thought about getting a name but that would mean he would be bound to somebody as a subordinate and he didn't want that the second was achieving the requirements to evolve himself but he currently didn't know how to achieve the requirements as he traveled through a ravine 3 dire wolfs surrounded him as they circled him, he looked between them wearily as he roar sending a shockwave finally through the ravine,causing it to bounce between the caves as the wolves whimpered in pain.
Daniel dug his right claw into the ground as he uprooted, his claw viciously, sending medium size boulders flying forward as 2 of the wolfs dodged the one behind Daniel the other dire wolf behind him lunged biting onto his tail Daniel barely felt it as his scales prevented weaklings like dire wolves from piercing his body as Daniel swung his tail slamming the dire wolf into the wall as Daniel charged forward steam rolling through the other dire wolves in front of him as they went flying through the air and crashing into the ground he roared in victory as he continued to travel as he thought about his current situation, even with his power, he is still weak. He would transcend the limitation by his species if a guy from his world that got turned into a slime can do it then surely he as a wyvern can go beyond him and these so called perfect beings called true dragons and become an being comparable to the God and majestic just as powerful and that was an promise not a declaration or boast this was something that was going to happen.
