Re: Registration Statement on Form S-1

Ladies and Gentlemen:

We have acted as counsel to Athena Technology Acquisition Corp. II., a Delaware corporation (the “Company”), in connection with the Registration Statement on Form S-1 (File No. 333-261287) (such registration statement, as amended through the date hereof, the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the offer and sale by the Company (the “Offering”) of (a) up to 28,750,000 units of the Company (the “Units”) (including up to 3,750,000 Units subject to the underwriters’ option to purchase additional Units), each such Unit consisting of one share of Class A common stock of the Company, par value $0.0001 per share (the “Common Stock”), and one-half of one redeemable warrant of the Company (each whole warrant, a “Warrant”), each Warrant exercisable for the purchase of one share of Common Stock, as set forth in the prospectus included in the Registration Statement (the “Prospectus”), and (b) all shares of Common Stock and all Warrants, in each case, issued as part of the Units. The term “Units” also includes any additional Units (and the underlying securities) that may be issued by the Company pursuant to Rule 462(b) under the Securities Act in connection with the Offering.

We have reviewed originals or copies of the Registration Statement, the Prospectus, the certificate of incorporation and bylaws of the Company, as amended through the date hereof (the “Organizational Documents”), the form of warrant agreement (the “Warrant Agreement”) proposed to be entered into by the Company and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agent”) that is filed as Exhibit 4.4 to the Registration Statement, and the form of Unit certificate filed as Exhibit 4.1 to the Registration Statement (together with the Warrant Agreement the “Transaction Documents”), and such other corporate records, agreements and documents of the Company, certificates or comparable documents of public officials and officers of the Company and have made such other investigations as we have deemed necessary as a basis for the opinions set forth below.

In making the foregoing examination we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as photostatic or certified copies, and the authenticity of the originals of such copies. As to all questions of fact material to this opinion, where such facts have not been independently established, we have relied, to the extent we have deemed reasonably appropriate, upon representations or certificates of officers of the Company or government officials. 

Based upon the foregoing, and subject to the qualifications, assumptions, limitations and exceptions stated herein, we are of the opinion that:
