Sonic The Hedgehog 2 XL

Introduction: Sonic the Hedgehog 2 XL is a joke ROM hack of Sonic the Hedgehog 2 for the Sega Genesis / Mega Drive by Captain Bozo. Its defining gimmick replaces normal Rings with onion rings that make Sonic progressively heavier as he collects them.

Gameplay & Mechanics: Eating onion rings causes Sonic to gain weight. As he becomes heavier, his movement slows, his jump becomes shorter, and eventually he can lose the ability to roll effectively. Consuming too many onion rings can kill him. Sonic can gradually burn off the extra weight by moving, and special monitors can help reduce it more quickly.

Key Features:

• Rings replaced with onion rings that directly affect Sonic's body size and movement.
• Increasing weight reduces speed, jumping ability, and mobility.
• Too many onion rings can become fatal, turning normal Ring collection into a risk-reward mechanic.
• Original Sonic 2 stages are recontextualized by the weight-management gimmick.

Sonic 2 XL is primarily a comedy gameplay hack built around managing Sonic's weight, not a hack that simply makes every Sonic 2 stage larger and more difficult.
