Dear Professor Rowan,

I’ve had a breakthrough. Juniper and I have been working on this for weeks now – and we’ve finally cracked it! However, with great success comes great danger. In case anything was to happen to me, I have enclosed a copy of my latest research entry below. I hope it finds you well.

Best wishes,
Oak

Entry 3:
Date: April 25th

13:32 It has finally happened. We have achieved Pokémon fusion. The idea of combining these powerful beings fills me with both excitement and trepidation. The potential consequences of tampering with such legendary creatures are immense, but the benefits of creating these new Pokémon are undeniable. By combining Pokémon types, we can potentially save them from poison, burns, paralysis and more.

To achieve fusion, I put the cells in a special golden-textured mixture and my trusty Togedemaru got things started with a small Zing Zap. The mixture contained: Ariados’ silk, a Braivery’s feather, magma from Slugma, Oddish’s leaf and a piece of Linoone’s fur.

But whilst this experiment was a useful proof of concept, specimens 643 and 644 are closely related. I imagine it will be harder with other species.
