In the anime, Ushiro fights for an entire day Zearth to die smiling for saving the earth and his sister more specifically.
In the anime, Kirie being the only pilot to pilot Zearth twice, proving during his second fight that he's easily the best pilot in the entire series, and then unmasking Machi as the uncontracted pilot. That last one doubles as a Dying Moment of Awesome.
Also in the Anime. Machi, how does she redeem herself? By helping Ushiro save Kana from the contract, killing Koyemshi and then forcing her way into the contract, fully replacing Kana.
While piloting Zearth, Waku, despite being wrapped in the grip of the enemy robot, puts his soccer playing experience to good use by delivering a powerful knee to the robot's weak spot until the robot falls over, then stomping it until it's defeated.
She's also pretty awesome in the anime, as Komoda has been murdered few hours before... and she goes out to fight anyway, refusing to give into despair and savingus despite how shitty her deal is.
In the anime, Moji, when faced with a robot that has two seemingly identical halves, manages to find out which one has the cockpit, destroying it in a risky but successful gambit. In the process, he also deduces that humans are piloting the robots.
Mako punching Oda in the face after taking her abuse for so long without so much as raising a clenched fist.
