He seems to be very self-centred and shows little care for those around him. During dogfights, he forgets about himself and ignores orders. He fires randomly as blood rises to his head, often being ridiculed as a chump.
On July 1, 2019, Champ distracted Erusean forces as they attempted to level the 444th Air Base. On July 4, he participated in Operation One Pair and assisted in crippling the Erusean base located in Roca Roja.
During Operation Two Pairs on July 12, 2019, Spare Squadron was sent in to help allied squadrons Cyclops and Strider break away from the airspace after they came under attack from Erusean MQ-99s. With the help of Trigger, the allied squadrons got out safely. However, after completing the operation, Champ was engaged by an Su-30SM piloted by Mihaly. He proceeded to dogfight with the pilot, ignoring orders from Bandog, and was quickly shot down by the old ace.
- In the Gamescom 2017 trailer, Champ is seen using an F/A-18F Super Hornet with the aircraft number 204 and tailcode "AD", this was later changed into a MiG-29A Fulcrum with the aircraft number 143 and tailcode "BN" as seen in the Gamescom 2018 trailer.
- Champ's tailcode, "BN" means he was possibly stationed in Bana City before his transfer to the 444th.
- During the cutscene following the first phase of Lighthouse, a MiG-29A sporting his livery can be spotted, flying in front of an Osean F-22A Raptor.
