Check out our All Star Tower Defense X Tier List with the best unit!

The Best Unit in ASTD X

1. Whitebeard – Best Full AoE Ground Unit

Whitebeard currently stands out as one of the most in-demand units in ASTD X. As a ground unit with Full AoE attacks, he’s incredibly effective in Infinite Mode and late-game Stages where enemy waves come fast. Testers report that his damage is extremely high and can carry your main team. Although he hasn’t officially appeared in the banner yet, make sure you save your gems—once he shows up, he’s worth the pull.

2. Sukuna – Top-Tier Hill Unit with Burn Damage

Sukuna is a hill-type unit (air attacker) with a powerful burn effect that deals damage over time. This extra effect pushes his performance above other hill units like Ulquiora or Frieren. Sukuna is praised for his wide coverage, being able to hit both air and ground enemies. If you want a unit that’s strong, flexible, and consistent across various game modes, Sukuna is a must-have.

3. Sung Jin Woo – Ground Unit with Summoning Power

Sung Jin Woo is already considered one of the strongest ground units in ASTD X. His ability to summon Egress, an additional source of damage, makes him even more powerful in clearing high-level waves. While the full potential of his summon hasn’t been fully tested, players strongly recommend picking him up as soon as he appears in the banner. For ground-based domination, Jin Woo is your guy.

4. Ulquiora & Frieren – Reliable AoE Hill Units

While they may not match Sukuna in overall power, both Ulquiora and Frieren are still very strong picks. Each has a circular AoE attack and high base damage. They work well in multiple situations and serve as great alternatives if you haven’t managed to get Sukuna. These two units are dependable for mid to late game content, especially in air-heavy stages.

5. Ichigo – Best 4-Star Unit with Strong Evolution

Ichigo starts as a 4-star unit but evolves into a solid 5-star with surprisingly high performance. In fact, many players find him outperforming some 5-stars in terms of AoE and raw damage during early gameplay. His evolution path is straightforward, making him a perfect fit for beginners. If you’re just starting out and need a core unit to carry you through, Ichigo is a smart choice.

Honorable Mentions: Other Useful Units Worth Considering

These units didn’t make the top 5 but still offer excellent value:

• Ramen Grill Master – The only money-generating unit right now. Not essential early, but extremely helpful for longer matches and late-game team setups.
• Zero / King Kai / Orurin – These are support buffers that boost team damage by up to 50%. They’re not needed early on, but they become essential in high-difficulty challenges.
• Kokushibo – A rare mythic unit obtainable through gacha. Powerful, but due to his low pull rate, not a consistent pick for most players.

In a game like ASTD X, power isn’t always about who looks the coolest—it’s about who delivers results. Units like Whitebeard and Sukuna are incredibly strong due to their wide AoE and flexibility. Meanwhile, Ichigo provides a reliable early game option for new players with great evolution potential. Keep saving your gems, monitor banners, and stay tuned for future updates—more powerful units are surely on the way. We’ll continue updating this list as the meta evolves!
