Armadillo was boasted as being as sturdy as a tank. However, sometime after the installation of a sauna in Mother Base, Armadillo stumbled upon MSF subcommander, Kazuhira Miller, having fun with Swan in one of the shower areas. This shocked him severely enough for him to faint, causing him to fall hard and be hospitalized for a month. MSF commander Big Boss learned of Armadillo's accident and its cause, ultimately having a fight with Miller due to him setting a bad example for MSF's soldiers, a fight that was witnessed by Paz Ortega Andrade.
