Muon

 is a Tier 5 Tank that upgrades from Iron and Pion at level 60.

Design
The is simply a combination of Iron and Pion. It looks very similar to Pion, retaining its signature ring and shields, but its plain Smasher shell is changed to match the color of Iron's unique shell. Its ring is also changed to the color of Iron's shell.

Technical
The retains Pion's shield ring with the added perk of debuff immunity.
