|Evolves from||Shellder (When Slowbro Mega Evolves)|
When Shellder Mega Evolves with Slowbro, the spikes on Shellder are reduced to four on the bottom section of its body, with the dark spots only visible on its middle section. It has an opening at its tip, allowing Mega Slowbro's tail to stick out, which it balances on due to its legs being engulfed.
Mega Slowbro's energy has gathered into Shellder, which has increased its hardness. This allows it to act as an armor so hard that nothing can scratch it.
