Throughout your adventure in Sonic Heroes, you'll encounter several common power-ups that provide temporary boosts or advantages. Knowing what each one does is crucial for strategic gameplay.

- Speed Shoes: Grants a temporary burst of extreme speed, allowing your team to move much faster. Ideal for clearing long straightaways or escaping dangerous situations.
- Invincibility: Makes your team temporarily invincible to all damage. You can still lose rings if you hit an enemy, but you won't lose a life. Excellent for pushing through heavily guarded areas or boss phases.
- 10 Rings: Adds 10 rings to your current count. Always a welcome sight, as rings are your health and contribute to your score.
- 20 Rings: Adds 20 rings to your current count. Even better than 10 rings!
- Team Blast Gauge Up: Fills a significant portion of your Team Blast gauge. Prioritize these if you're close to unleashing a powerful Team Blast.
- Barrier: Provides a temporary shield that absorbs one hit of damage without losing rings. A good defensive item for tricky sections.
- Magnetic Barrier: A more advanced barrier that not only absorbs one hit but also attracts nearby rings to your team. Very useful for maintaining your ring count.
- Extra Life: Grants an additional life. Always a high-priority item to collect, especially in challenging stages.
Remember that power-ups are temporary, so time their activation wisely. Don't waste an Invincibility power-up on a section with no enemies, for example.
