A kid named Kiyoshi Tendo was artificially made by Dai-Shocker to be the perfect weapon against the riders. He is able to use all the zecters and hyper zecters as he is a combination of some A.R. riders and worms D.N.A.. Although it was thwarted by Soji Kusakabe which is the alternate version of Soji Tendo.

Not really knowing what to do with him although he would like to take care of him but he is busy fixing things on a multiverse level so he gives him to his friend who is similar to him which is Professor Paradox. Professor Paradox then gave him to Max Tennyson to grow normally and become a good person and gave Kiyoshi some farewell gifts together with Soji Kusakabe.
