受《黑袍纠察队》士兵男孩气质启发的复古硬派超级士兵 Codex pet:短棕发、军绿色战甲、圆盾、傲慢坏笑和老派宣传英雄感。他强壮、自负、嘴硬又爱摆谱,动作包含站立待机、眨眼、抱臂、敬礼、盾牌防御、背盾奔跑、落地冲击、雪茄耍帅、坐姿偷懒、胸口能量爆发等。特殊待机帧里,他趴在木桌上对着一堆白色面粉胡闹,旁边有面粉袋和碗,像一个荒诞狼狈的黑色幽默梗。

What Are Codex Pets?
Codex pets are virtual companions that live in your OpenAI Codex CLI terminal. Use /pet hatch to hatch a new pet, or install a custom pet package to personalize your coding companion. Custom Codex pets are defined by a pet.json file and a spritesheet.webp image — anyone can create and share one. Browse the gallery above to find community-made pets, copy the install command, and run it inside Codex to get your new companion.
