Thats in real life, but in powder toy it goes trough fission.
Kerponaut; Deuterium undergoes fusion not fission as deuterium is an isotope of hydrogen.

I must sadly say that it hardly even works. Theres little to no deuturium to start any good fission and most of the plutonium doesn't even go trough fission. The hydrogen doesn't get enough heat nor pressure to fuse. Also it would be recomendable to use breakable clone rather than just clone.
